Was playing a Bomb Jack on MAME and amazingly I've only just realised after all these years that the music from level 2 sounds exactly like Lady Madonna by The Beatles: EDIT: Not only that but just I've noticed that Bomb Jack has "BJ" across his chest. The actual level itself (after 0.55): Turns out the developers managed to license the song for the game though in some reissues and ports they use a tune from Mighty Bomb Jack. Another Beatles song in a game: Soundalikes: ^ Don't quite get it myself. ^ I guess I can now its pointed out. Any others...that isn't Rock Band related.
